Samples of DNA arecollected, and the four DNA bases ofA, G,C, and T are coded as1, 2,3, and4, respectively. The results are listed below. Construct a 95% confidence interval estimate of the mean. What is the practical use of the confidenceinterval?
2, 2, 1, 3, 4, 4, 4, 3, 3, 1
What is the confidence interval for the population mean ?
<<
(Round to one decimal place asneeded.)
What is the practical use of the confidenceinterval? Select the correct choice belowand, ifnecessary, fill in the answer boxes to complete your choice.
A.The confidence interval can be used to estimatethat, with 95% confidence, the interval from X to X actually contains the true mean DNA base of all people.
(Round to one decimal place asneeded.)
B.The given numbers are just substitutes for the four DNA basenames, so the numbers do not measure or countanything, and they are at the nominal level of measurement. The confidence interval has no practical use.
C.The confidence interval can be used to estimate that 95% of all people have DNA bases between X and X
